Too many obstacles to overcome and no one to design it. The 6.4 was easier than the 6.7 and it didn't happen. The newer fuel systems are so complex and the emissions are a roadblock if not removed. Tuners and dpf deletes are being watched close by the EPA making it an even more impossible task.

Assuming you have a deleted truck, what would be the hold up to running a veg system on a 6.7? I'm bored and going to start looking into what the difference is in the fuel systems. I'll be honest I love the hell out of my new truck. If she was running on veg I'd have about all I could ask for.

Hell the dodge dealers are telling the new ecodiesel guys they can run veg in them. I'd imagine there is a lot more involved with those trucks. Maybe the dealers are just full of it. But I've had 2 guys tell me the dealers used that as a selling point

I do have 1 client running veg in a 2012 6.7 Dodge. He removed the whole exhaust system and had a mechanic that stuck with the whole process. The computer had to be reprogrammed to live without the exhaust system and regeneration mode.

He spent weeks trying to figure out after run. I do not know if he ever got past that one. He was working with BD trying to figure out how to do it last time I heard from him. I sold him the kit with the knowledge that I would not be able to help him. He was OK with that. The plumbing of lines is not the problem.

The DPF and regeneration is a pain in stock form. I'd imagine it wouldn't work at all with the veg. Before I bought my truck but was looking at new rams, I read that the epa had filed law suits against a few delete /tuner companies. They stated they would no longer sell tunes or deletes, but would continue to support current customers. Luckily my truck has been deleted and retuned. I have a strait pipe from the turbo back. And the egr/cooler have been disabled. Problem is I do not have the tuner, nor do I know anything about the tune I'm running. I'm not really a big fan of that.

I've read a few accounts of guys running diy systems without issue. It's a thought I guess.
